I’m not going to pretend I’m the biggest “Green Lantern” fan out there. The character has never really interested me, and I always fond his power to be kind of ludicrous (the guy can make anything with his ring, but he usually makes stupid things like giant green hammers or fists to punch bad guys with). Having said that, I could be wrong but I believe “Green Lantern” co-star Blake Lively may or may not have let a potentially major plot point out of the bag in a recent Vogue article.

Need I say it? POTENTIAL SPOILERS BELOW.

So Lively, who is playing Carol Ferris, the love interest of Green Lantern’s Hal Jordan (played by Ryan Reynolds) in Martin Campbell’s upcoming big-budget movie, has done an interview with Vogue. It’s one of those puff celebrity pieces, but Lively goes on to say something very interesting in the interview that the boys at CHUD picked up. Here it is:

The adventure begins in the Vogue offices when I am bidden to look at the fittings shots of Blake Lively, which reveal a body sublimely toned for her upcoming role as Carol Ferris (a.k.a. ultravillain Star Sapphire) in Martin Campbell’s Green Lantern, based on the DC Comics superhero introduced in 1940. “All I want is to be a hero to my nephews and nieces,” Lively says, laughing. “I’m going to be the coolest aunt ever.”

Lively has been rehearsing with a stunt coordinator who works on the Bond movies and with gymnastic acrobats from Cirque du Soleil. “Our director likes it real—the fights close and dirty,” she explains, and for added veracity aerial stunts are being filmed in the rig created for The Matrix. “I’m 40 feet in the air, spiraling around. That’s the best workout you can ever do because it’s all core,” she tells me. “You do that for ten minutes and you should see your body the next day! It’s so exhilarating, so thrilling—and nauseating,” she adds, all of which promises to stand her in good stead for the surf experience to come.

Star Sapphire is the name of several supervillains in DC Comics, all connected in origin. Within DC continuity, an immortal race of warrior women (the Zamarons) were depicted as having the ancient tradition of choosing physically identical mortals from across the cosmos to serve as the host body for their queen. The woman they choose to serve this role is called Star Sapphire. She is given the queen’s symbolic weapon; a crystal resembling an actual star sapphire that grants the user powers similar to the power ring of a Green Lantern.

Basically, a sorta female version of the Green Lantern, which makes her the perfect villain for Green Lantern, aka Hal Jordan, aka Ryan Reynolds, aka I think Blake Lively has just told the world that her character will turn into the Star Sapphire in the upcoming movie and fight the Green Lantern.

Or not. A number of commenters on the CHUD article claims to have read the script, and Star Sapphire never once makes an appearance. Could rewrites have written her in? Or maybe the Vogue article just sort of got it wrong or tangled up?

We’ll know for sure when “Green Lantern” opens June 17, 2011. Oh, who are we kidding. We’ll know for sure well before that.
